The sacrifice failing miserably would be the crucifixion. I don't know if you noticed since then mankind hasn't been very kind to each other, animals & the planet. Not an entire failure. If we are to believe the bible we could guess at least it was enough to stop God from flooding the earth again killing everyone except whoever was next in line to build a boat. Kinda scary when you realize Jeff Bezos just built a huge yacht.
Genesis 9:11
I establish My covenant with you; and all flesh shall never again be eliminated by the waters of a flood, nor shall there again be a flood to destroy the earth.
He promised NOT to, Knight.
